Question

#3. For the reaction, will the concentration of the acetate ion increase or decrease if: HC₂H₃O₂(aq) <---> H⁺(aq) + C₂H₃O₂^-(aq)

    a. acetic acid removed? ________     b. hydrogen ion added? _______

   c. water added? _________                d. sodium hydroxide added? _________

Answer 1

3)

       HC₂H₃O₂(aq) <-----------------> H⁺(aq) + C₂H₃O₂^-(aq)

    a. acetic acid removed decreases  

b. hydrogen ion added    decreases

   c. water added     decreases          

     d. sodium hydroxide added    increases

Explanation :

a & b)

on addition of reactant or removal of any product acetate ion concentration increases. on addition of product or removal of any reactant acetate ion concentration decreases.

c)

on addition of water acetate ion dilution increases. no acetate ions are coming out.

d)

on addition of NaOH. OH- react with H+ . so product concentration decreases.
